The Data Center
Introduction to Cloud Computing

4. Carnegie Mellon
What is a Data Center?
 As an organization’s IT needs to grow, the total cost of
ownership (TCO) of it’s IT resources grows
 Resource management, power, cooling scaling, fault‐
tolerance, space (real estate) becomes an issue
 Solution? Consolidate your IT resources into a data
center!
Introduction to Cloud Computing

5. Carnegie Mellon
Data Center Goals
Introduction to Cloud Computing
 Minimize floor space, maximize resource density
 Keep the equipment in a safe and controlled environment
 Resources must be easy to access physically and manage,
components must be individually replaceable without
disrupting normal operations
 Optimize operational costs

6. Carnegie Mellon
Physical Layout
 Equipment is placed in racks
 Equipment is designed in a modular fashion to fit into
rack units (1U, 2U etc)
 Servers, blade enclosures, networking and power
equipment etc can be loaded into these racks
1U Server

A Quick Introduction to Servers and
Blades
Introduction to Cloud Computing

9. Carnegie Mellon
Servers
 Computers that provide “services” to “clients”.
 Typically more powerful and have more resources than
desktop computers.
 Organizations requiring more and more physical servers
to provide various services (Web, Email, Database, etc.)
 Server hardware is becoming more compact.
Introduction to Cloud Computing

10. Carnegie Mellon
Servers for Datacenters
 For large‐scale installations, server hardware is getting
more compact to help with manageability, scalability, and
power and cooling
 Organizations would like to conserve the amount of floor
space dedicated to their data centers.
Introduction to Cloud Computing

11. Carnegie Mellon
Blades and Blade Enclosures
 A blade server is a stripped down server computer with a
modular design
 A blade enclosure holds multiple blade servers and
provides power, interfaces and cooling for the individual
blade servers.
 A single rack can hold up to 42 1U servers
